Limit number of GnuTLS handshakes per connection.
* gnutls.c (gnutls_log_function2i): Convenience log function.
(emacs_gnutls_read): Use new log functions,
`gnutls_handshakes_tried' process member, and
`GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
attempts per process (connection).
* gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit. Add
convenience `GNUTLS_LOG2i' macro.
* process.c (make_process):
* process.h: Add integer `gnutls_handshakes_tried' member to
process struct.
